Ammonia from power plant emission gases via reduction of the nitrosyl complex de Fe(II)EDTA by S(IV)


The full reduction of nitric oxide in nitrosyl complexes of Fe{Il)EDTA by aqueous bisulfite solutions has been investigated under a variety of conditions. It was found that about 85 % of the initial NO is converted into NH_4 by prior incubation of FeEDTA(NO)^(2-) in excess bisulfite at 300 K, pH = 6.8 during 4 hours, followed by a second stage in which the reaction mixture is brought to 373 K, pH= 1 for 6 hours. Partial oxidation of the metal center reveals an active role for FeEDTA^(2-) in this process.
